Teacher's field guide
What This Cluster Means
What Students Need to Do
- Students represent linear relationships from words, tables, and graphs using algebraic rules. They find unknown values and show solution sets on number lines or coordinate planes.
What Mastery Looks Like
- Students isolate variables with valid inverse operations and check solutions by substitution. They graph lines accurately, use open or closed boundaries correctly, shade solution regions, and connect equations, tables, graphs, and contexts.
Common Misconceptions
- Students may reverse the inequality sign incorrectly, or forget to reverse it after multiplying or dividing by a negative. They also confuse slope with the y-intercept, use the wrong boundary line, or shade the wrong side.
How to Assess It
- Use an exit ticket: solve and graph 3x - 5 ≤ 10, then graph y = -2x + 4 and label its slope and intercept.
Lesson moves
Ways to Teach It
Use balance mats and algebra tiles to model 2x + 3 = 11, then mirror each move symbolically.
Ask students to compare y = 2x + 1 and y ≤ 2x + 1, then explain what the shaded region means.
Play Graph Match with cards showing equations, tables, graphs, and inequalities, requiring students to justify each set.
Give a phone plan with a monthly fee and per-gigabyte charge, then write and graph cost and budget rules.
